Weirdest thing and I haven't seen anyone else mention it. My Check Engine light comes on all the time with every tank of gas. With the Check Engine light on, the Traction Control Off light comes on AND THE ELECTRIC CONTROL TRANSMISSION DROPS A GEAR OR TWO AND WON'T SHIFT ANYMORE. Have to stop the car and restart. Very serious safety issue. Causes me to slow down in traffic with no warning. Anyone hear about anything like this? I can not detect an action or process that triggers this. Seems totally random.
